    The number under the radical (the radicand) is also known as the discriminate. You can determine what kind of solutions based on the discriminate. If it is negative, you will have two complex solutions, or roots. If it is zero, you will have one real solution. If it is positive, you will have two real solutions. Based on your choices and given that the radicand, or discriminate, is positive, you have to decide if your solutions are rational or irrational.

    So now you have a 50/50 choice, c or d.
